‘Everyone cried': Paralysed woman describes walking after pioneering treatment
A woman who was paralysed as a result of an illness has described how 'everybody cried' when she was able to take her first steps following a pioneering treatment.
Claire Trivedi received a type of spinal cord stimulation during a small clinical trial which enabled her to take a few steps using a walker.
The 48-year-old from London was paralysed from the waist down in 2017 when a group of abnormal blood vessels in her spinal cord burst.
The mother of two is one of 10 spinal cord injury patients who took part in a study assessing new stimulation technology.
While taking part in the trial, she was able to restore some functions which were initially thought to be lost after her injury.
The technology has been described as a 'hearing aid for the nervous system' and works by stimulating the 'dormant' spine below the patient's injury, combined with 'activity-based therapy'.
Experts said the results of the small pilot study were 'game changing'.
And Spinal Research chairwoman Tara Stewart said the study suggests 'it's now time to stop talking about spinal cord injury as being incurable'.
Ten people aged between 21 and 68 with different levels of spinal cord injuries took part in the study, which has been published in the journal Neuromodulation: Technology At Neural Interface.
All participants in the Pathfinder 2 trial, funded by Spinal Research, made significant improvements in their upper body strength, trunk control and balance.
And some saw major gains in hand grip and dexterity and lower body functions after using Onward Medical's ARC-EX Therapy combined with rehabilitation.
Patients took part in the study for more than a year at Neurokinex rehabilitation facilities in the UK and each had 120 sessions where they were given transcutaneous spinal cord stimulation.
The technology delivers electrical pulses through the skin to stimulate the spinal cord which means that signals weakened or interrupted by a spinal cord injury can drive movement.
It is coupled with intensive physical therapy, tailored to each patient.
Some of those who took part in the trial saw bodily function return a decade after injury or illness.
Researchers said that the improvements did not plateau, which suggests further benefits may be achieved with extended treatment.
Ms Trivedi said: 'I was told my injury was complete and I just had to get used to my situation, but I refused to give up.
'I dreamed that one day I might take a few steps and my dream came true.
'About 10 weeks before I finished the trial, I took my first steps just using a walking frame, without any leg supports. Everyone cried.
'I was putting my all into the trial and was being rewarded. Even though it was really slow I could see improvements. My legs were getting stronger and I had hope.
'And although all the gains haven't continued, I definitely think the stimulation had a massive impact on my rehab and I can't wait for it to be licensed in the UK.'
Ms Stewart added: 'This therapy is not a silver bullet – it works on spared spinal tissue so results will vary widely, and it does need to be paired with proper active rehabilitation over a consistent period of time.
'Even so, this is a game changing moment. It's now time to stop talking about spinal cord injury as being incurable and to stop telling people with this injury that nothing can be done.'
Jenny Suggitt, co-investigator of the study, said: 'Participants who have completed the study at this point are seeing changes in their motor function – so their standing ability, walking, core control and sensation changes, as well as changes to their autonomic function – so bladder, bowel and sexual function.
'We are seeing recovery in participants who are over 10 years post injury, and they're regaining function that they never thought possible.'
Co-investigator Jane Symonds said: 'Transcutaneous spinal cord stimulation has been described a little bit like a hearing aid for the nervous system, so it's enhancing the signals that the nervous system is receiving.
'And so it's hoped that if somebody, for example, is trying to get some muscle activity in their legs to be able to stand or walk, that when the stimulation is in place, there is a greater level of excitability in the spinal cord, and therefore those nerve impulses are more likely to reach their target destination, and hopefully enable people to use those muscles.
'It has the potential to be a game changer and we're hoping that it's a real breakthrough for people with spinal cord injury.'
Dave Marver, chief executive of Onward Medical, said the study 'provides critical insights to the spinal cord injury community, demonstrating that improvements resulting from ARC-EX Therapy extend for at least one year, with no observed plateau'.
Harvey Sihota, founder and chief executive of Neurokinex, said: 'There is no doubt that spinal stimulation technology will take spinal cord injury rehab to the next level, bringing even more meaningful functional improvements that offer people greater independence.'
Spinal Research is also funding three other UK studies involving use of implantable and external spinal cord stimulation systems.
Ms Stewart said: 'With proper investment in the spinal research field we could see significant progress towards a cure for paralysis in the next five to seven years.'

Natterjack toad makes 'wonderful' comeback at national park
The natterjack toad, the UK's loudest amphibian, has made a "remarkable comeback" at a national park following a conservation project.A total of 28 toadlets were recently counted at Blackmoor, Hampshire, in the South Downs, following the reintroduction programme, which started in is the first time natterjack toads have been recorded breeding at the site in 50 toad, which has a distinctive rasping call that can be heard up to a mile away, had previously only been found on a single site in the national park at Woolmer Forest. In neighbouring Sussex it is considered locally Amphibian and Reptile Conservation (ARC) charity has led work to provide new suitable territory for the included creating shallow ponds and restoring heathlands for the introduction of cattle grazing to create "perfect conditions" for them to return. Jack Harper from ARC said: "We are delighted that everyone's hard work is beginning to pay off and that the future of this fascinating species is looking brighter in the region."This is a great first step to recovering the species within the national park and a good blueprint for future reintroduction efforts."Olivia French, heathlands project team leader for the park, said it was a "wonderful success story for nature recovery" that shows "wildlife can thrive if given half a chance".The future for natterjack toads was "certainly looking brighter than it was", she said, with a breeding population at Woolmer and now Blackmoor as well. "This area is the last heathland bastion for this iconic species and extending their habitat range is a big step forward in stopping the species becoming locally extinct," she added. Ms French said that 75% of breeding sites in the UK had disappeared in the past toads are now almost exclusively confined to coastal sand dune systems and grazing marshes in north-west England and the Solway Firth in added: "They are one of the most at-risk species from climate change because of rising sea levels, so this makes the comeback in Hampshire all the more significant."

Changes to ARC grants will make it harder for Australia to combat Trump chaos, researchers warn
It will be tough to attract international research talent if prestigious Australian Research Council fellowships are axed under proposed changes, researchers say, with lack of funding making the nation not 'match fit' to take on Trump-led uncertainty. The overhaul proposed axing most standalone positions in favour of shorter fellowships that are 'embedded' into projects. It would reduce the number of competitive grant programs from 15 to six, ending prestigious three-year fellowships for early-career researchers and four-year future fellowships for mid-career researchers. According to an ARC discussion paper, 'Traditional four-year fellowships concentrate a significant amount of funds on a small number of individual researchers.' The proposed replacement of two-year 'embedded fellowships' would distribute funding 'to more people and projects', it suggests. The decision has been criticised by academics amid global research uncertainty brought by the Trump administration's attacks on science and education in the US. The changes would 'harm international recruitment and retention,' said Prof David Schlosberg, director of the Sydney Environment Institute at the University of Sydney. 'Two years is not going to attract people. What they are proposing for a replacement is inadequate,' he said. 'For a young person, that's not really enough time to get into a project and make progress, produce results and really build a career,' said Aidan Sims, a distinguished professor of mathematics at the University of Wollongong. 'Three years is really a minimum for that.' Unlike in North America or Europe, most early-career researchers in Australia are not directly funded by the universities where they work. 'The only source of postdoctoral positions in the Australian system is via the research grants,' Sims said. 'The new model will very substantially reduce the opportunities not only for us to attract excellent researchers from abroad … but also to provide opportunities for our emerging superstars to kick off their careers.' The proposed overhaul comes amid drastic US government cuts to research funding, including to Australian projects, which is driving American researchers to move internationally. In Europe, the European Research Council has doubled its relocation allowance for researchers outside the EU, while universities there are also actively recruiting US academics. An Australian researcher who runs social media accounts under the moniker ARC Tracker said: 'It's going to be very hard to convince any new talent to come – even Australians overseas to come back – to a two-year research position where the longer term prospects are really not very clear at all.' 'We're not match fit to fight this uncertainty that is now global in research. We don't have our own research house in order, and can't take opportunities because of that,' they said. Sign up for Guardian Australia's breaking news email 'The Europeans have their house in order, and they're taking an opportunity that they see because they're ready to.' Australia's investment in research and development – the current subject of a separate review – is 1.7% of GDP, lagging behind the OECD average of 2.7%. Schlosberg, who was recruited to Australia from the US 15 years ago, said Australia took for granted its current high level of research impact. 'Australia really does well in the international rankings but that's because of past investment,' he said. 'If we don't continue to invest, those rankings are going to plummet.' Prof Sharath Sriram, president of Science and Technology Australia, said the peak body welcomed the 'overdue' ARC review to simplify its grants programs, but said: 'We are concerned about the unintended consequences.' 'By the time you're into the meat of your project you already looking for your next job or your next grant.' Sriram called for more clarity around employment lengths, as the ARC's new schemes will allow early career researchers to draw a salary 'for the full duration of the project' from any grant they are awarded. 'I think that's not clearly articulated,' he said. Schlosberg praised the introduction of a 'really well designed' scheme for early-career researchers, which will fund 'high risk, innovative work where people without track records can apply'. Public consultation on the proposed changes will close on 13 April. The ARC, which will deliver its final report to the government in mid-2025, was contacted for comment.

Kent: Paralysed man regains movement in breakthrough trial
A Kent man paralysed from the waist down has partially regained bowel and bladder control thanks to breakthrough UK Woodall, from Rainham, was paralysed in 2016 after falling from a bypass after a night 33-year-old was one of 10 people to take part in a recent Pathfinder2 trial, funded by charity Spinal Research, using electrical stimulation to "excite" the spinal cord and attempt to create movement."[The trial] gave me back control over muscle groups I never thought I'd move again, including my right hamstrings and hip flexors," he said. "I've also regained some bowel and bladder control - something I was told in hospital after my accident might never happen."Just knowing when you want to use the toilet is such a massive thing for your independence and mental health."The fact that the gains have continued after the trial is really encouraging and I can't wait to see where this goes."The participants took part in 120 sessions using the technology - known as ARC-EX saw significant improvements in upper body strength, torso control and balance, according to Spinal Research chairwoman Tara Stewart said: "This therapy is not a silver bullet."It works on spared spinal tissue so results will vary widely and it does need to be paired with proper active rehabilitation over a consistent period of time."Even so, this is a game changing moment.
